I saw it on Facebook, its a beasty

[RogueTwoRobots]

Weighs 13.5kg in this video, all that's left to go back on is armour, which currently weighs 600g. Still haven't done any weight-saving though and I can downgrade some of the armour, so I reckon it'll all be fine. Enjoy

That's got some serious kick, wow! I'd prefer not be under it when it fires now, damn...

[plargen]

great vid, that does look like its got a good bit of power

[adz600]

like the video, do you have a job !!!!!
looks really good motor still looks abit loose on mounts possibly lots of flex in video, cant wait to have an axe off some time soon if I ever get round to fixing my cracked chassis thanks to ls4
good job

[RogueTwoRobots]

Thanks guys. Yeah the motor looks a bit loose (especially at the bit when the axe head gets stuck) but it's solidly bolted into the machine; the flex is coming from the polycarb baseplate. Hopefully it's strong enough for the job, but with enough flex so as to absorb the forces when the arm hits.

Definitely up for an axe-off (get Little Hitter and Asgard in there too), got more chance of the axe bot still running after an event than I do with Drumroll (a drum-off will take place one of these days!)

Just uploaded a couple more photos, just to better show the interior with the motor fitted:





It's absolutely mahoosive in relation to all the other components. The drive is a little bit squiffy at the moment though; not sure if that's to do with the 2.2kg of motor being off-centered or the fact that I've got two different speedos controlling it (had to switch one of the drive Victors onto the scooter motor and use the 25A Botbitz from the old axe drill motor for the drive). Will probably fit TZ85s for all three channels soon so will see what happens when that's done and everything's properly bolted back together again.

are you using a speed controller for the axe? if so, how are you applying full power instantly?

Yeah I'm using a Victor 883 on the weapon at the moment (will be changing to a TZ-85 when I move across to them). Just controlling it by throwing the transmitter stick to the left or right as quickly as my fingers will allow, so not completely instantaneous, but the difference is negligible. However in the 10 years I've had the transmitter, I've never once used its trainer switch (which is a spring return switch) so I'm planning on rewiring that onto the channel pot so that I can flick the switch to get instantaneous power yet still retain proportional control for retract and demos.

Cheers Dan, no limit switches fitted on it (they'd probably get destroyed) but I've found that just judging it by eye seems to be sufficient. Because the joystick and switch both spring back to the centre/off position, it's easily enough to let go when it's either hit something or reached its travel. Will be adding some rubber absorption/protection to the chassis at the travel limits though.

Looks really good so far Jamie. Have you got any limit switches on it?

Hi Jamie, I like your new weapon videos.
Have you tried experimenting with a larger gear-ratio for the axe? I'm guessing the sprocket on the motor shaft already has the fewest teeth possible?
